A knapsack lifter of a tractor relates to a lifting mechanism for lifting personnel or articles. A hydraulic pump of the tractor communicates with a distributor through a hydraulic oil pipe, the distributor communicates with a short supporting arm oil cylinder, a long supporting arm oil cylinder and supporting leg oil cylinders through hydraulic oil pipes, and stretching and retracting of the oilcylinders are controlled through the distributor. A long supporting arm is connected with a short supporting arm through a right rotating shaft, and the short supporting arm is connected with a bearing frame through a left rotating shaft. The long supporting arm oil cylinder is assembled between the long supporting arm and the short supporting arm, and the short supporting arm oil cylinder is assembled between the short supporting arm and a supporting frame. Four anti-toppling supporting legs are assembled on the bearing frame, and the supporting leg oil cylinders are assembled on the anti-toppling supporting legs. A hanging basket is connected with the long supporting arm through a hanging basket rotating shaft and connected with a long pull rod, and the long pull rod is connected with ashort pull rod through a pull rod connecting plate. The long support arm oil cylinder and the short support arm oil cylinder stretch out and draw back to drive the long support arm and the short support arm to rotate with the right rotating shaft and the left rotating shaft as shafts respectively, and lifting of the hanging basket is completed.
